Ruby WIN32OLE_RECORD#typename用法及代码示例

WIN32OLE_RECORD#typename #→ String object

返回VT_RECORD OLE 变量的类型名称。

如果 VB.NET ComServer 项目中的 COM 服务器如下：

Imports System.Runtime.InteropServices
Public Class ComClass
    Public Structure Book
        <MarshalAs(UnmanagedType.BStr)> _
        Public title As String
        Public cost As Integer
    End Structure
    Public Function getBook() As Book
        Dim book As New Book
        book.title = "The Ruby Book"
        book.cost = 20
        Return book
    End Function
End Class

那么， WIN32OLE_RECORD#typename 的结果如下：

require 'win32ole'
obj = WIN32OLE.new('ComServer.ComClass')
book = obj.getBook
book.typename # => "Book"
